Abstract
The utility model discloses a fully closed coal powder sampling device which comprises a grooving tube, an auger, a sampling bottle, end covers, a reversible motor or a handle. Both ends of the grooving tube are sealed by end covers, the auger is positioned in the grooving tube, and the reversible motor or the handle is arranged on a shaft which is extended from one end of a sealing cover. A sample outlet is arranged on a closed section of the grooving tube, wherein the closed section is positioned outside a powder falling tube, and the sampling bottle is arranged at the point of the sample outlet. A lower wall at the top end of the grooving tube is provided with a material discharging opening. The utility model has the advantages that original coal powder is cleared cleanly through rotating the shaft of the auger by the handle, and then the collected coal powder is input in the sampling bottle by clockwise rotation. Powder amount in the bottle is observed until the required amount is obtained, the defect that amount estimation is needed is compensated, and the certainty of sampling amount is enhanced. Because the whole process is carried out in the fully closed state, the overflow and the drop of the coal powder do not exist, and environmental protection is improved. The utility model has the advantages of civilized operation, convenience and succinctness.
Description
One, technical field
The utility model is applied to the power station pulverized coal preparation system.Coal cinder is accompanied by the hot blast medium and carries out wind, powder separation behind abrasive dust, extracts the usefulness that powder sample is done chemical examination by this device when coal dust falls.
Two, background technology
Existing coal fines sampling apparatus is the product of sixties design, is installed on the powder sinking tube of pulverized coal preparation system, and uses till today always.It is made up of outer tube, stopple coupon, fixture block, handle etc.When not taking a sample, 90 ° of elongated slot that makes progress on the outer tube and the dislocation of the elongated slot on the stopple coupon; Rotate stopple coupon during sampling, make the elongated slot of the elongated slot alignment outer tube of stopple coupon, the coal dust of whereabouts falls in the stopple coupon by elongated slot, extracts stopple coupon out by operating personnel coal dust is poured in the vessel.The sampler design of this kind structure is still owed rationally, and the coal powder collection amount can't be seen when reality is used, and needs operating personnel to estimate according to actual conditions, and therefore uncertainty is arranged; When extracting stopple coupon out, because the pressure in the powder sinking tube, coal dust can outwards be overflowed by the outer tube pore, adds to take out Guan Shihui and take coal dust out of and scatter around, causes environmental pollution, and therefore the not feature of environmental protection is arranged; One time collecting amount may not reach required amount, and this is repetitive operation several times, and therefore not simplicity is arranged.
Three, summary of the invention
1, goal of the invention: the purpose of this utility model provides and a kind ofly can extract coal dust at regular time and quantity, makes whole process have more the full cut-off formula coal fines sampling apparatus of the feature of environmental protection, simplicity.
2, technical scheme: for achieving the above object, full cut-off formula coal fines sampling apparatus described in the utility model comprises slotted-tube, auger, sampling jar, end cap, reversible electric machine or handle, the slotted-tube two ends are by end cap seal, auger places in the slotted-tube, reversible electric machine or handle be contained in auger from an end gland bonnet stretch out the axle on, be provided with outlet on airtight section outside slotted-tube is positioned at powder sinking tube, sampling jar is installed in this sample outlet position.
Lower wall is provided with discharge gate on the top of described slotted-tube.
Principle of work of the present utility model is: reach slotted-tube in the powder sinking tube and make on the slotted-tube long rabbet up, drive at first reverse rotation of auger by handle or reversible electric machine, outmoded powder ash in the slotted-tube is discharged from discharge gate, be rotated in the forward auger again the coal dust that newly falls into is extracted out from slotted-tube, and be discharged in the sampling jar from outlet.The quantity of powder sample can directly be observed from sampling jar, or is carved with gage mark on sampling jar.
3, beneficial effect: the utility model compared with prior art, have the following advantages: (1) is cleaned out original coal dust by handle rotation screw-conveyer-shaft, remake the clockwise direction rotation with the coal dust input sampling jar of collecting, powder amount in the observation bottle gets final product until required, remedy the defective that needs estimation, improved the determinacy of sampling amount.(2) all under full closeding state, carry out because of whole process,, improved the feature of environmental protection so there be not the excessive and unrestrained of coal dust.(3) operation civilization, convenient, succinct.
Four, description of drawings:
Accompanying drawing 1 is the utility model structural representation that reversible electric machine is housed
Accompanying drawing 2 is the utility model structural representations that handle is housed
Five, embodiment:
In conjunction with the accompanying drawings, the designed full cut-off formula coal fines sampling apparatus of the utility model comprises slotted-tube 1, auger 2, sampling jar 3, end cap 4, reversible electric machine or handle 5.Slotted-tube 1 is a steel pipe, and two ends are by end cap 4 sealings, an end shutoff, other end external thread structure.Auger 2 is housed in the slotted-tube 1, on its axle that stretches out, reversible electric machine or handle 5 is housed, airtight section of slotted-tube 1 outside powder sinking tube, there is the powder of falling mouth the termination, connects sampling jar 3, lower wall is provided with discharge gate on the top of slotted-tube 1.
Claims (2)
1, a kind of full cut-off formula coal fines sampling apparatus, it is characterized in that it comprises slotted-tube (1), auger (2), sampling jar (3), end cap (4), reversible electric machine or handle (5), slotted-tube (1) two ends are sealed by end cap (4), auger (2) places in the slotted-tube (1), reversible electric machine or handle (5) be contained in auger (2) from an end gland bonnet stretch out the axle on, be provided with outlet on slotted-tube (1) is positioned at outside the powder sinking tube airtight section, sampling jar (3) is installed in this sample outlet position.
